For example:
（首段）The three lines in the chart each show the changes in the proportion of the elderly people to the population of the USA, Sweden and Japan from 1940 till today. Also the chart gives predicted date for the trends.
(主體段)Since 1940, the proportion in the USA has been slightly higher than that in Sweden at any given time, while that in Japan was always the smallest. Specially, the figures for the three countries in 1940 were 9%, 7%, 5% respectively. The changes in the proportion in the USA and Sweden are featured mainly by steady increase although since 1980 the USA experienced somewhat declines. By contrast, Japan did not see increase substantially, sending it to a peak of 5% in 2007, the same as in 1940. According to the prediction since 2000, the upward trends will have been obvious in the three countries, but in Japan will soar at the fastest speed. Till/By 2040 the figure will have reached 27%, compared with25% in the USA and 23% in Sweden.
另一篇文章，主要展示最值的表達
In the term of the length of the Underground Railway System (URS), that in London ranks first among the six in that it reaches 394km, almost 36 times longer than that in Kyoto, the shortest. The second longest is in Paris (199km).
Focusing on the open date, we see that once again London URS was strikingly earlier than all other counterparts. Put it accurately, London opened the URS as early as in1863, 37 years earlier than that in Paris. By contrast, the youngest is LA who did not start to run URS until 2001.
説明文注重語言的流暢，簡潔。在圖表作文中，不追求詞藻的華麗，只追求表達的清楚。
注意點：1.沒有必要寫出每條信息，要辨別關鍵特徵
2.段落劃分要合理（得分點）
3.銜接和過渡詞很重要
一整篇文章的例子：劍五P75
To be located in the town centre,S2 is in the town centre, a non-traffic zone. As result, it is only accessible by the railway whereas the main roads are unavailable. Moreover, it is hemmed out the houses, meaning it’s convenient for the dwellers to do some shopping. In addition, it is closer to the south industry but far away from the north.
Unlike S2, S1 will be set in the countryside, where both the railway and main roads are ready. But the 44000 people from Bransdon and Crandson find it not easy to reach S1, although it is connected by the railway with Crandson. Furthermore, this site is far away from the two industry areas. However, it is convenient for those who live in Hindo.
To sum up, the two sites are different in many aspects/ways.
